Things I liked: First impression is wow this is one solid feeling gun. Well made gun, heavy but feels comfortable and balanced. Stock, trigger grip and fore grip are unique to me. Found them well made, adjustable, ergonomically pleasing, loaded with accessories and fun to shoot with. This has scary power for the house or backyard. Mines a 22 and between 180 and 140 psi it was peak. I used a sled to sight a weaver 4 x 28 on high see through rings. Allows use of nice open sights and scope. once its dialed the groupings were less than inch at 25 yard in my basement. As power wanes it drops but apples to apples its accurate.

Things I would have changed: The air feed is a little problematic for me with a hand pump. The air probe doesn't screw in and counting on those two rubber rings to hold the air in seems sketchy.

What others should know: Serious weapon, not for kids. Very accurate and very loud. Not really a shoot in the neighborhood gun. Its very loud and that will dray attention. Push the pellets all the way in the revolving clips. Twilight Zone moment but I used same exact pellets as the other poster. It shot better, looked cooler, is more comfortable and better made than I expected.

Just bring your cylinders to your local paintball shop, they'll outfit you with an adapter for your probe, and you can get it filled at any paintball shop for anywhere from $2.50-$5.00 per fill, aside from this solution, it's either splurge for a scuba tank set-up, or bust a nut with the pump.
